Perpendicular Lines Definition (& Consequence)

This applet naturally leads students to see what it means for lines to be perpendicular (by definition). It also contains a 2nd component in which students can easily see/discover that if 2 non-vertical & non-horizontal lines graphed in the coordinate plane are perpendicular, then the product of their slopes is always -1.
